Module:Citation/CS1/Configuration

Documentation icon Module documentation[view] [edit] [history] [purge]

This configuration file contains various data that controls the functioning of Module:Citation/CS1 and hence the way that Lua-based citations are generated.

It is divided into three sections:

  1. A translation table that contains most of the literal strings that may be included in Lua-based citation. If editors are copying this Module to another wiki using a language other than English, then they should translate each of these values into that language.
  2. A list of error conditions specifying what text to display, what category to include (if any), and what help page section to refer to.
  3. A list of ID handlers specifying the recognized document IDs, such as ISBN, DOI, etc., and how to format them.
